SINGEING-IVI'ACHINE.

Specification of Letters Patent.

Patented March 27, 1 906.

Application filed March 26,1904. Serial ITO-200,186. v

To all whom it may concern: f Be it known that I, HENRY KRAEMER, a citizen of the United States, residing at Nazareth, in the county of Northampton and State of Pennsylvania, have invented a new and useful Singeing-Machine, whereof the following is a specification, reference being had to the accompanying drawings. My invention relates to a machine designed primarily for-subjecting shaped textile products to a singeing operation.

Themachine which I have shown and will describe is especially adapted to the singeing of'stockingsf but thein-vention is not thus limited, as it may be adapted for use in connection with other similar textile products.

In order to perform the singeing operation to the best advantage, the-stocking 1s placed upon a block or form, and it is while carried by the block that the singeing operation is performed. My invention includes the devices by means of which the block, wit-h its stocking,is carried between the singeingjets. It also includes 'a stripping device by means of which after the'singeing operation is 'performed the singed stocking is stripped off its block and allowed to fall into a convenient receptacle. It also includes a reversing device comprising parallel setsof rolls running in opposite directions with a transfer device by means of which the block carrying the stocking after passing foot first through the singeing device is'reversed in motion, so as to pass top first through the stripping device; By employing this it is possible to arrange the point of delivery of the blocks from the stripping device in immediate proximity to .the point where they are to be again fed into the machine after having received another stocking, which is placed upon the block by 9.1% operator stationed at that end of the mac ine.

- V In the accompanyingdrawings, Figure I is a plan view of a singeing-machine embodying my invention. Fig. II is a side elevation of the same. Fig. III is an enlarged rear elevation. Fi IV is an enlarged vertical section along the ine IV IV, Figs. I and III. Fig. V

is a partial section along the line V V, Fig. I. Fig. VI is a detail view of certain parts hereinafter moreparticularly described.

The machine is'mounted upon a rectangular frame A, which may be of squared timber supported upon standardsa a. At the front end of the frame there is provided a broad table B,- projecting from and supported by the frame This table may conveniently be used to carry the stockings which are to be successively placed by an operator upon blocks in order that they may be passed through the singeing-machine. tangular frame. is a rectangular housing 0, in which are rovided all the necessary journals for the rol ers and shafts which will be described. At the front end of the housing is formed a projecting shelf 0, which is over the table B. At that side of this shelf from which the stockings are fed to the machine it is provided with a pair of guide-flanges c c. by

means of which the block D, with a stocking pulled over it, is accurately fed between the rollers at the point where it is to commence its course through the machine.

7 The shaft E carries a roller e, a pinion e and a set of fast and loose pulleys e 6 from which it may be driven. The shaft F carries a c'ompanion'rollerf and a pinion f meshing with I the pinion e It is carried in open bearin s and is situated over the shaft E, so that To ler f rests with its weight upon roller e. The shaft G carries a roller g and a pinion g, by .means ofwhich it is driven from the pinion e with interposition of the gear-wheel g The shaft H has open bearings and carries a companion roller h, resting on roller g, and a pinion h, which meshes with the pinion g. Between the two pairs of rollers thus described are the burners, consisting of two rectangular sets of gas-piping, one above and the other below the path which the block D, with its stocking, takes as it passes from one pair of rollers to the other. has jets projecting from its lower edges, and likewise the lower set I has jets projecting from its upper edges, so that'as the stocking passes between them both top and bottom surfaces are simultaneously effectually subjected to the singeing operation.

The parts which I have thus far described constitute the singeing apparatus proper. Immediately alongside of this is the stripping apparatus, which in some respects is 'a counterpart of the singeing apparatus and which I will therefore next describe.

The shaft E carries in addition to the fast and loose pulleys by which it is driven a pin- The upper set I 6o Supported upon the recion and the roller e (5% Fig. V.)' Over wheel g. It has a companion roller 7i ,restmg in open bearings immediately above the roller 9 The rollers which constitute the stripping apparatus are located in the direct on opposite to those which constitute the smgeing apparatus, the blocks, with their stockings, which have passed through the former being passed in the reverse direction through the latter.

it are a pair of stri ping-blades (see Fig. V) which are adj ustab y mounted in such position that as the block passes between the rollers it is drawn between the blades, the interval at which they are adjusted being such as to allow the block to pass freely through, while the edges of the blades draw the stocking from the block, the block passing back upon the shelf 0 ready to be received by the operator and to have another stocking placed upon it, while the stocking which has been stripped from it falls into a receptacle provided for the purpose. It will be noted that the blades i i are inclined so that their opposing edges are directed forward in the direction in which the block moves between them. This serves to prevent the possibility of any tearing of the obj ect to be stripped from the block.

I will now describe the transferring and reversing device by which the block which has passed through the singeing apparatus is transferred laterally from the line of motion of said singeing apparatus to the line of mo tion of the stripping apparatus with an accompanying reversal of the direction in which the block travels.

j j 3' j j are a series of feedrollers, the shafts of which carry the corresponding sprocket wheels J J J 2 J J J, all of which are upon the same side of the machine as that occupied by the stripping apparatus. This series of sprocket-wheels is driven by a sprocket-chain from a sprocket-wheel mounted upon the shaft G. The upper portion of this sprocket-chain passes alternately above and below the sprocket-wheels of the series, so that while it drives the rollers j, j, and j forward the rollers 7' 3, and 7' are driven backward. The rollers may preferably be clothed with any rough material, as sandpaper.

K and K are parallel and similar endless carrying-chains each provided at similar intervals with projecting studs or rollers 7c. Both of these endless chains are carried by and pass around sprocket-wheels mounted, respectively, upon the longitudinal shafts L L L The chains are driven by the rotation of the shaft L, the motion of which is derived as follows: At the rear end of shaft L is a sprocket-wheel Z. Parallel to shaft L is a short longitudinal shaft M, which carries a sprocket-wheel m and a ratchet-wheel m, both of which are fast upon shaft M. The ratchet-wheel is controlled by a detent m The shaft M also carries a pair of fast and loose pulleys m m An endless chain it passes around sprocket-wheels Zm, hanging oosely, so as to form both an internal and an external fold. Within the internal fold this chain carries a pulley-block a, from which depends a weight N. The fast and loose pulleys m m are driven by a belt 0, which turns at right angles around the rollers 0 0 and passes around the pulley 0 upon the shaft which carries the sprocket J from which it derives constant motion. When the belt is on the fast pulley, sprocket on is driven so as to move the chain in the direction to lift the weight N. \Vhen the belt 0 is on the idle pulley, sprocket m is kept from reverse rotation by the engagement of the spring-pressed detent m with the ratchetwheel m. The pulley-block it, upon which the weight N is hung, carries 011 top a vertical rod n around which is set a coiled spring a A belt-shifter p is mounted upon an arm upon a rock-shaft P, encircled by a coiled, spring n, which normally tends to rotate the shaft P to shift the belt O from the idle to the fast pulley. The rock-shaft P carries a horizontalarm 1) through a hole in which the rod a freely passes. The descent of this rod is permitted by an intermittent motion of the sprocket-wheel Z, as will shortly be described. The coiled spring a is freely interposed between the top of the pulley-block n and the arm 2), and as the lifting of the weight proceeds this spring is gradually compressed between the two until its tension, overcoming the tension of the spring a, is sufficient to rotate the rock-shaft P to shift the belt upon the idle pulley; but when the rod a again descends the spring n" gradually ceases to press against the arm 7) and allows the spring a to rotate the shaft'P, moving the shifter 12 to shift the belt 6 from the idle to the fast pulley, whereupon the weight is again raised. This intermittent motion of the sprocket Z is part of an intermittent rotation of the paired carrying-chains K K. The weight N tends constantly to effect this rotation; but an intermittent check is placed upon it by reason of an escapement-arm q, set upon the shaft L As this arm rotates, it contacts successively with the projecting ends of a pair of slide-rods q (1 The ends of these sliderods are pivoted to the opposite ends of a centrally-pivoted lever r. This lever has a third arm 1?, which is connected by a link r to the projecting end of the shaft H, which carries the roller h, the other end of shaft H being counter-depressed in its open bearing by a spring 1*. When this roller is in contact with its fellow roller g, the lever 1' is in the position shown in Fig. II, where the slide-rod q projects at its end so as to interfere with the further downward rotation of the arm (1, holding it in the position seen in Fig. IV. When, however, a block, with its stocking, is fed under the roller h, is raised,

and by its elevation the lever'r is rocked so as .to-withdraw the rod g sufficiently to allow downward rotation of the arm g, at the same time ,ho wever,"p'rojecting the endjof the sliderod 1 so as to cause it to check the rotation of the arm 9 as soon as it has reached the from its path, so that the arm 'q is allowed to make nearly a complete revolution, (as the weightNzconstantly tends to cause it to do,)

- untilit comes into the position shown in Fig.

IV, and the operation repeats itself. I

It will be evident that by the operation of l the parts thus described the intermittent feeding of the blocks throughthe rollers of the singeing apparatus causes the endless chains K K to have an intermittent motion,

one complete revolution of the arm occasioning' a movement of the chains e'qua ing in extent the distance between the studs k k. Each such intermittent feed permits the weight N .to descend a corresponding distance, and'as a result after a number '0 such successive intermittent feedings have oc- .curred it is necessary to have the weight reraised. This is accomplished by the intermittent operationof the sprocket-wheel m, which has been described. As a block emerges from the singeing'apparatus it is car- I ried backward by the rollers j j" 9' until its point comes into contact with a fixed stopS.

As soon as the end of the block leaves the rollers g h the chains K K commence their motion, and the studs 7e70, engaging the block, carry it sidewise to about the middle line of the machine, as shown in Fig. I'.- Here it remains until the entrance of another block under the-roller 'h' permits afurther slight motion of the carrying+chains The next movement of the chains consequent upon the issuance of the end of this second block from between rollers g andv h carries the'first-menj 3' whichar'e rotating backwardly; In order to preventthe gradual movement of the block onto these rollers, a pair of lifting-fingers T T are set upon the longitudinal shaft 1.. The shaft L carries cams l 1 running against cam-surfaces t t on the under side of the fingers. As the motion of the chains K K occurs which-is to carry a block over to the rollers 1' '7' j the fingers are slightly elevated by the cams, lifting the block as it moves sidewise a little above the rollers; This position is maintained until the full extent of the sidewise movement has carried the block directly over the line of the rollers. Too great sidetioned block as far over as the line of rollers 3' wise motion is prevented bythestop-rollers was. At the proper moment the cams allow the fingers to fall, thereby placing the block suddenly upon the rollers, whichimmediately carry it to the stripping apparatus.

Having thus described my invention, I
